In December 1917, a small troop of soldiers was sent on a secret mission to an outpost in the north of Sweden. It’s a remote area, the snow is heavy, and skis are the only means of transportation. Their assignment is to bring supplies to the Finnish army fighting against the Russians. On arrival, they find the compound deserted and the telegraph sabotaged. Inspecting the area, they find terrifying signs of brutal combat. Isolated and unable to communicate with the outside world, they now are faced with an unknown threat to fight off – or perish.
